No, this isn't a rant about anti-immigration economists. I just wanted to share the following clip from the movie Clueless that I've showed in class to introduce my discussion of immigration. It helps to reinforce to my students the importance of the argument that led to a conclusion. To often they think because they got the right answer they deserve 100 percent, even if everything leading them there was wrong.
The statesman who should attempt to direct private people in what manner they ought to employ their capitals would not only load himself with a most unnecessary attention, but assume an authority which could safely be trusted, not only to no single person, but to no council or senate whatever, and which would nowhere be so dangerous as in the hands of a man who had folly and presumption enough to fancy himself fit to exercise it. -Adam Smith
